Problems solved by technology

However, the microemulsion cutting fluid also has the following disadvantages during use: the oil discharge performance of the microemulsion cutting fluid is poor. It becomes an emulsion, which makes the microemulsion cutting fluid lose its superiority and greatly reduces the service life of the cutting fluid

Abstract

The invention discloses a micro-emulsion cutting liquid with a good oil removal performance. The cutting liquid is composed of the components in percentage by weight as follows: 5-7% of diethanol amine, 4-6% of triethanolamine, 7-9% of boric acid, 5-7% of 60% petroleum sodium sulfonate and 6-8% of fatty alcohol-polyoxyethylene ether with the hydrophile-lipophile balance of 2-4, 5-7% of sulfonated monopol soap, 8-10% of polyalcohol oleate, 3-5% of vulcanized aliphatic ester, 10-12% of naphthenic oil with kinematic viscosity of 10-32 mm<2> / s at 40 DEG C, 0.3-0.5% of benzotriazole, 0.2-0.4% of silicone emulsion and the balance of water.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a microemulsion cutting fluid with good oil discharge properties. Background technique [0002] According to the chemical composition of oil, cutting fluid is divided into two categories: non-water-soluble (oil-based) fluid and water-soluble (water-based) fluid. Oil-based cutting fluids have better lubricating properties and poorer cooling effects. Compared with oil-based cutting fluid, water-based cutting fluid has relatively poor lubricating performance and better cooling effect. [0003] The emulsion combines the lubricity and antirust properties of oil with the excellent cooling properties of water, and at the same time has good lubricating and cooling properties, so it is very effective for high-speed and low-pressure metal cutting where a large amount of heat is generated. Compared with oil-based cutting fluids, the advantages of emulsions are greater heat dissipati...
